I can't find a video, but there was an episode of the corny 80s show "Out of This World". It was about a half human/half alien girl with superpowers. Anyway, in the episode I'm talking about she starts having nightmares about turning into a monster because of her alien DNA. In one of the dreams, the monster appears as a hideous marionette that jumps on her and starts biting her face. Scared the crap out of me when I was a kid.
